I bought a laptop (MSI GX60 3BE) last month and i tried to install Linux 14.04 on it. There was a problem with the graphic card that finally I resolved. But after that, I had another problem. The batery lasts 30 minutes, more or less (I used W7 too and the battery lasts at least 3 hours in a moderated use). What Linux should I install or how can I fix this problems? I always use Windows and now I want to prove something new. Please help and sorry about my english!
